Vintage Cary Grant and Sophia Loren Romantic Comedies

Just finished watching two of them.  Houseboat, where Washington lawyer and widower, with three small cute children, meets up with Sophia Loren, who first charms the children, and then wins Cary Grant's heart.  With a few amusing mishaps, like when moving a house, they get it stuck in a grade crossing, and then a diesel powered express train roars thru, blowing the house to splinters.  Which results in the family moving into a beat up house boat on the Potomac. 
   Then there is The Pride and the Passion, a movie set in Napoleonic war Spain.  Spanish guerrillas come into possession of an absolutely humongous cannon.  They set about dragging the mountain of metal clear across Spain to the siege of some-where-or-other.  Sophia Loren is the BFF of the guerrilla leader  (Frank Sinatra).  Cary Grant is the English naval officer who is the only man with the guerrilla army who actually knows how to work the gun. 
   Heartwarming movies the likes of which they don't make anymore.  Houseboat is the better of the two, Sophia Loren gets a better role.
